Consider returning and depending on interfaces in `ISearchClient` about algoliasearch-client-csharp

[rmendoza-prescriber]

Would be nice if this change can be made in the next release, I'm having issues trying to write unit test using this client

+1 to this. It is very difficult to unit test interactions with the ISearchClient. Also related to #745

Hello,

We will release in few days a new major version of all Algolia C# Clients. In this version, all clients returns interfaces to enhance testability.

I'll reply in this thread as soon as the client is released.

The Alpha version is now released on Nuget.

If you have time, we need customer feedback about this new version. It's still not GA so you may not want to use it in production.

There is no more deps on Newtonsoft, all Algolia APIs are now available (Insights, Recommend, Query Perso, ...) and all models and routes are synced.

To help you migrate, there is a Migration guide.

Happy to help in your migration process !
